John Gill Commentary Ezekiel 22:4

"Thou art become guilty in thy blood that thou hast shed, and art defiled in thine idols which thou hast made; and thou hast caused thy days to draw near, and art come even unto thy years: therefore have I made thee a reproach unto the nations, and a mocking to all the countries." — Ezekiel 22:4 (ASV)

You are become guilty in your blood that you have shed
Not only she contracted guilt by the innocent blood she shed, but she was tried and found guilty; her guilt was notorious, plain, and evident, as well as exceeding great, and much aggravated:

and have defiled yourself in your idols which you have made :
she not only made them, in doing which she sinned; but polluted herself with them, by worshipping them; her mind and conscience were defiled with them; and which brought such a stain and pollution, as could not be removed by anything that she could do: there are both pollution and guilt in sin, and neither can be removed but by the blood of Christ; and, unless removed that way, punishment must follow:

and you have caused your days to draw near, and are come even unto your years ;
to full age, to ripeness for judgment; she had hastened by her sins her days of affliction and distress appointed for her, and was come to years of maturity to suffer for her sins; the years of her captivity, which would soon take place; years in which she would have no pleasure:

therefore have I made you a reproach unto the Heathen, and a mocking to all countries ;
who, instead of praising them for their idolatry, would deride them for leaving the God of their fathers, which they did not; and insult over them in their affliction and distress, though they joined with them in idolatrous practices.
